Its not that hard, just dont expect it to be get finished and throw it on the boat and take off. You will have to tweak it to get everything right.

Here is the one me and furdown built. Just now getting it tweaked and ready. ![](http://i288.photobucket.com/albums/ll185/brock2013/EF5355FA-33A4-44BA-8B8E-DABBC4B664FE-5064-0000067D70C7FAB2.jpg)

Man that looks awesome is it a belt drive or chain drive? Where did you get your parts from? Is it steel or aluminum? I built most of the frame from scrap steel I had laying around the farm. Because im cheap I went with a chain drive instead of a belt drive and I spend $626.00 total. The ebgine is a 16hp Duramax engine from Maxtool.com wich cost $289.00 delivered and has and electric start. The prop is a Hill Marine and I purchased off of Ebay for $160.00. The rest of the parts such as chain, sprocket, bearings, trottle cable were purchased localy at places like Tractor Supply and Grainger. Just Like Furdown said you will need to make some changes after you run it. Since I took the pictures I re did the Skeg Plate and made a custome exhaust for the engine. The old skeg caught grass and the new exhaust added a quicker response to the trottle. Ive got a cousin that has a 40hp Kohler mounted on a go-devil frame and yes he can run circles around me in speed but he cannot run shallower than me due to the amount of weight he has. I had a great time building the engine and am looking forward to realy giving it a work out this season. If you have any questions please feel free to ask me anything. Also like DOMB52 said Mudmotortalk.com is a great resource. Thier are several guys there that build thier own engines and will be more than happy to give out advise. ![](http://i1195.photobucket.com/albums/aa389/blmaloney/photobucket-1448-1348666122076.jpg) ![](http://i1195.photobucket.com/albums/aa389/blmaloney/photobucket-10922-1347467342445.jpg)

Ours is made out of 3/16" steel. The box is a piece of 6x4 rectangular tubing. The rest was cut out of plate. We went with a belt drive. It works great we just have to get the small things tweaked and fixed. We have a 420cc predator engine from harbor freight and a mud buddy 10x8 prop. It's not that hard to build. We ended having to rebuild some mounts that wouldnt work. Just be ready to do some tweaking and you should be fine.

Do you have a cost analysis twixed building your own Vs. buying a used one or new one? I understand a certain satisfaction is derived from DIY. However in my latter years I kind of shy away from DIY as a lot of the times it bites my hiney.

I have about $550 in motor and prop, I already had the steel. I don't know the price of bearins and pulleys but you can get some from mcmastercarr.com for about 75 for bearings and about 100 for pulleys. I'd guess that I have about $1000 into it. For a similar hp surface drive most are up over $2000 or $2500.

Also how did you harnes the propeller thrust on the shaft? Im currently running a 1.6 to 1.0 drive ratio and I used a trust bearing at the end of the drive shaft.

I'm running a 1.5 to 1 reduction. It runs pretty good. I haven't had the chance to really try it out much. We are using flanged mount bearings that have set screws that lock down on the shaft.

Man I need to start building these...how do you go about registering them? Ounce you get a motor finished there are a couple of forms that you can down load from TPWD and after you fill them out you call and schedule a appointment for the Game Warden to do an indpection. After that they will issue a title for the motor.

what kind of speeds are yall getting?
Ime getting around 14 to 15 empty just running around. With 1 person, Dog and gear it will get around 11 to 12. With 2 people and gear it will get around 8 to 9. The boat I have it on is 25 years old and the bottom is very beat up with hooks on every rib. I think with a cleaner hull I would get better speeds. this compared to the same boat running a 20 HP Evenrude wich was getting 18 to 19 empty, 15 to 16 with 1 person and gear and 11 to 12 with 2 people and gear isnt to bad. Most of the hunting I do is within 2.5 to 4 miles from the ramp to its a 15 to 20 minute boat ride. The true advantage to the motor isnt speed its the ability to run shalow. when my out board would run out of water I was draging my boat loaded with gear another 1/4 to 1/2 mile and with this motor I can run all the way back which makes for a much easier hunt which I like.

I have a question for yall. Is it a direct drive, or is there some type of clutch so the prop isnt spinning the whole time? The only clutch set up i can think of would be a centrifugal clutch like on a go kart; but i havent had much luck with finding them in the bigger sizes. What do yall use?

You can put a centrifugal clutch on it if you want. Ours is a direct drive so the prop spins when it is cranked up. I just hold the prop out of the water when I crank it and lower it down to take off.
